MOP-WRINGER.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application iled July 26, 1916. Serial No. 111,518.

To all whom t may-concern:

Be it known that T, HOWARD C. BnowN, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Mop- Wringers; and T do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mop wringers, and the object of the same is to produce an improved guard and means for projecting it across the free ends of the rollers when the mop is withdrawn therefrom in the act of wringing. This object is carried out by the construction described and claimed below, and shown in the drawings wherein- Figure 1 is a plan view, Fig. 2 is a sectional view on the line 2-2 of Fig. 1 with the parts in their normal position, and Fig. 3 a similar section showing the mop withdrawn. Figs. 4 and 5 are details of parts referred to below.

I have shown this mop wringer as mounted in a bucket or tub T which may well be rectangular in plan view as seen in Fig. 1, and which is of sufficient size to receive both rollers and the mechanism connected therewith, and yet leave space at what might be called the open end of the rollers so that the soiled mop can be inserted in such space and rinsed in the water within the tub, and then passed between the rollers and wrung out for a new use; but I do not wish to be limited to this specific mounting of the wringer, nor to the tub itself.

What I will call the fixed roller 1 has its trunnions mounted in fixed bearings, and in Fig. l the forward trunnion 2 is shown as journaled in a bearing which is carried by a bracket 3, whereas the rear trunnion could be journaled in a bearing carried by the rear wall of the tub if the latter were rectangular as shown. Vhat I will call the movable roller 4 has its trunnions 5 mounted in bearings in a yoke 6 whose arms are slidably mounted in guides which latter may also be carried by a bracket 7 and the rear wall of the tub, and which are of sufficient length to permit the yoke to have some considerable movement. Behind the yoke is disposed a spring S which is here shown as a bowed spring whose extremities slidably engage the yoke and whose center is adjustably connected with the side wall of the tub by a bolt on which runs a thumb nut 9, and when the latter is set up the tension of the spring is increased. This spring normally bears the yoke and the movable roller forward so that the latter contacts with the fixed roller, and both of them and their bearings stand within the tub well above the water line.

For retracting the movable roller I provide a foot piece or treadle 10 from which rises a rod 1l passing through a guide 12 to a bell crank lever 13 pivoted at 14 to the tub, and the other arm of this lever is connected by a link 15 with the yoke 6 in any suitable way. Pressure on the treadle therefore causes the yoke to be retracted against the tension of the spring, and the roller 4 is thus moved out of contact with the roller l; but when the foot is removed the spring restores the parts to the position seen in Fig. 1.

The numeral 20 designates a guard, which is a plate having an oval hole 21 through it and teeth 22 along the lower side of the hole. This guard is slidably mounted in a guide 23 which may well be carried by or formed in one of the arms 24 of the bracket 3, and the hole or slot 21 passes loosely over the trunnion 2 of the roller 1, which trunnion between the roller and the bracket 3 is provided with a spur wheel 25 for engaging said teeth 22. A spring 26 connects the rear end of the guard plate 2O with some fixed point as the back of the bracket 3, and normally retracts this guard so that its front end 27 stands about flush with the front or inner side of the roller '1.

In use, the operator inserts the soiled mop into the tub at the space beyond the brackets 3 and 7, as seen at the bottom of Fig. 1, and rinsesout the same. Then stepping on the treadle 10 to retract the movable roller 4, the mop stick and mop head are moved bodily between the rollers; after which the foot is removed from the treadle and the spring 8 presses the yoke and movable roller forward as will be clear. Drawing upward on the mop stick thereafter causes the rotation of both rollers, and the trunnion of fixed roller l causes its spur wheel 25 to move the guard plate 20 in its guide 23, this movement commencing the moment the rotation of the roller 1 commences. that the front end 27 of the guard is projected across the space between the two rollers, which space is the thickness of the The result isl mop head, and therefore no part of the mop cloth or head can pass out from between the rollers endwise while it is being drawn upward through them. As soon as it is wholly withdrawn the spring 8 presses the roller 4L forward or inward while the spring 26 retraots the guard 20 and rotates the roller 1 reversely; and the parts are automatically restored to the position shown in Fig. l, ready for renewed use.

What I Claim is:

l. In a mop wringer, the combination with a roller mounted in Xed bearings and having a spur Wheel on one trunnion7 a roller mounted in movable bearings, yielding means for pressing it toward the firstnan'ied roller, and means for manually retraoting it; of a guard plate adjacent one end of the lirst-named roller and having an elongated opening with teeth in its lower Copies of this patent may be obtained for five cents each, by addressingK the side, the former inclosing said spur wheel and the latter engaging with it.

2. In a mop wringer, the combination with a roller mounted in fixed bearings and having a spur wheel on one trunnion, a roller mounted in movable bearings, yielding means for pressing it toward the iirst-named roller, and means for manually retractng it; of a guide adjacent one end of the firstnamed roller, a guard plate slidably mounted thereover and having in it an elongated opening inclosing the trunnion of said roller and provided with teeth along one side engaging said spur wheel, and a spring for retraeting said plate so that its front end stands normally flush with the inner side of this roller.

In testimony whereof I afIiX my signature.
